The Tamiya Mini 4WD Cylindrical Weight, branded by 3Racing, is engineered as a 4.3 gram mass damper for racers refining transient response and chassis damping. Its compact cylinder profile allows targeted installation with minimal aerodynamic penalty.
Engineered to interface with MS, MA and AR chassis platforms, the damper adds concentrated mass to locations that influence roll centre behaviour and vertical compliance. Install using standard Mini 4WD fasteners and verify clearance to avoid interference with suspension or bodywork.
In competitive settings, this damper assists in reducing midcorner oscillations and improves tyre contact under load, aiding lap time repeatability. Use in combination with cornering roll adjustments and roller setup for a balanced, race-ready chassis.
